IMPROVEMENT IN ENVELOPES.

The Schedule referred to in these Letters Patent and making of the nasal.

I, J. PATTON THOMPSON, of Philadelphia, county of Philadelphia and State of Pennsylvania, have invented a new and useful Device for Opening Envelopes, of which the following is a specification.

The object of my invention is to provide a simple device to be attached to envelopes, which forms part of the same, for the purpose of opening the envelope, and at the same time to be a medium for advertising the business of the writer.

Figure l is an ordinary envelope, showing my device applied.

Figure 2 is an edge view'ofan envelope, showing an opening through which the slip passes.

Figure 3 is a detached view of my device.

Figure 4 is an ordinary envelope, showing a difi'erent method of applying my device.

Figure 5 is an edge view of envelope shown in fig. 4.

Figure 6 is a detached view of my device as applied to envelope shown in fig. 4.

Figure 7 is a view, showing another method of applying my device to the envelope.

Figure 8 is ancdge view of same, showing the opening through which slip passes.

Figure 9 is a detached view of my device as shown in fig. 7. I

To enable those skilled in the art to make and use my invention, 1 will now proceed to describe the same.

When the stock is cut to form the envelopes A, D, and E, as shown in iigs. 1, 4, and 7, and edge views figs. 2, 5, and 8, the cutters U, G, and O are formed. at the same time from stilf card-board or other suitable material the said cutters being provided with slips S, S, and S, the cutters are laid on the stock before the same is folded and pasted to form the envclope with the slips S, S, and S extending through the openings 0,0, and O.

The cutters O, 0, and O- are intended to have printed upon them the business advertisement of the party or parties using the envelope, as shown in fig.6.

In opening the envelope the flap of the same will have printed upon it instructions, as shown'in fig. 7, so as the same will instruct the receiver to pull upon the 'slip, which draws the cutter against the edge of the envelope, which acts as a knife and opens the envelope at which ever end slip protrudes through, and at the same time calls the attention of the party opening the envelope to the advertisement printed on the cutters. 7

1 do not-wish to limit myself to, any particular form of cutter or at any point of the envelope the slip may protrude, as there are many ways that the cutters can be arranged and the same result produced.

What I claim, and desire to secure by Letters Pat ent, is

The cutters G, O, and 0, provided with slips S, S, and S arranged, in conjunction with the envelopes A, D, and E, so as to operate as and for the purpose specified.

In testimony whereof I have hereunto signed my name in the presence of two subscribing witnesses.

J. PATTON THOMPSON.
